Sybil Attacks were somewhat my concern when suggesting the introduction of an optional CAPCHA sustem.
It seems to me that until sentient activity is verifiable in a digitaluzed matrix-8, then one could play with the valves and levers all day long without being ever certain if one is monitoring bot traffic or not.
Just because there is a sentient precence does not exclude them originating from some sweat shop somewhere. That is where the reputation scheme would have greater weight. Its benifits would only.be exerted if a verified sentient is at the wheel; driving the traffic so to speak. 😎
